G. H. WINGATE SPECTACLES AND SPECTACLE FRAMES Filed Aug. 26, 1932 Patented Ian; I, 1933 This invention consistsiofs. improvements inor relating to .spectacles and spectacle l frames, and has for. 'oneof fitsa-.objectsi.t'o: provide spectacles which will afford the fullest view whenthe eyes are turned in all directions. Considering the case -of a sportsman, it is often important to glance at the wearer in front elevation, the line of junction of lens and frame has a somewhat flattened top which slopes outwardly and upwardly from a point near the bridge towards the temple.

In a preferred form of this invention, the spec-l tacle frame and/ or lenses are so shaped that looking directly at the wearer in front elevation, the line of junction of lens and frame'is of a curved triangular form with an upper edge sloping upwards and outwards from a point near the bridge towards the temple.

According to a feature of the invention, the apex of the curved triangular lens is near the bridge, the upper edge of the lens slopes outwardly and upwardly towards the temple, the outer edge of the lens although curved is substantially vertical, anda third corner of the triangle (although smoothly curved) comes at a point slightly outside the vertical line vof the centre of vision. It will be. understoodthat although reference is made to a triangular-form the edges of the lenses are smooth curves.

The invention is illustrated diagrammatically and by way of example in the accompanying drawing, wherein: I

Figure '1 is a front elevation showing one form of spectacle frame and lenses according to the invention,

Figure 2 is a plan view of the frame shown in Figure 1; and I Figure 3 is a perspective view of one form of motor goggles according to the invention.

Like reference characters designate like parts in all the views.

Referring first to Figures 1 and 2, the spectacle frame which may be composed of any convenient material, for example, metal, such assteel, tortoiseshell, or the like, comprises two lens frames.

Each Iens'frame IO, 'an'd -the' l'en's :14" carried by the same is 'ofcurved-triangular formy with the apex 16 of each triangle lying in proximity to i the bridge '11. From each apex lfi whichv is smoothly curved, the upper side 18 of each lens frame, and also the upper edge of each lens slopes upwardly and outwardly towards the adjacent temple of the wearer when the spectacles located at a point which lies outside a vertical plane indicated by'the line 24 passing through 'the'centre "of vision, when the spectacles are in.

The described spectacle frame and each lens am-A me innisiamncisimms rr r :we i na r I Pl i i iistgza 193a,;seiia1i-i6; 63o, 15t i therefor is thus so shaped that when-viewed in front elevation on the wearer, the line of .junction of each lens and the frame,or the upper edge of each lens, has a somewhat flattened top vwhich slopes outwardly and upwardly from a point near the bridge towards the temple, there- 1 by "affording a full view when the eyes are turned upwards, Further, owing to the shape of each lens frame and the contour of each lens being of curved triangular form with the upwardly and outwardly sloping upper edge, the spectacles will afford the fullestview when the eyes. are

turned in all directions, which is particularly. im-.-

portant in the case of sportsmen, as bodily finovement of the head upwards, downwards or sideways, may thereby be obviated. when changing the direction of vision. The lenses are sufficiently large. to give a very full view, and they are. preferably of toric or meniscus form, but in some cases, so-called flat lenses may be used. The

lenses are preferably made of splinterless glass,

i; e. laminated glass.

As shown in Figure 2, the spectacle frame may be so'shaped' that the general planes of the two rim frames 10 as viewed'in. plan, form. an angle with one another of suchimagnitude,"

In this construction the frames 10 are shaped as described above with reference to Figure 1, and may carry clear or tinted pieces 28 of any convenient translucent material, such as is usually employed in motor A flexible bridge 30 connects the frames 10 which may be provided with fell; 32, or other convenient. material for making a closefit with the face of the wearer, Alternatively, some other form of guard instead of felt or the like, may

I claim:--- v A spectacle frame for the reception of a lens, abridge connected to the frame substantially on a line passing horizontally through the center of vision, the upper and lower frame parts beyond the bridge inclining respectively upwardly and downwardly from such bridge throughout substantially their full lengths, the relatively outer margin frame part being substantially parallel to: a line passing vertically through the center of vision, the diverging upper and lower frame parts gradually increasing the area of the sight opening from the bridge connection to the outer margin of the frame and providing the maximum area of sight opening beyond a vertical line pass- :ing through the center of vision relative to the bridge, with such maximum area of sight opening increasing upwardly and downwardly from such verticalline passing through the center of vision to the outer margin of the frame; I GERALD HENRY WINGA'IE;
